Description

Technical Field

[0001] This invention relates to the field of lunar sample collection technology, and more specifically to a stacked extraction and adhesion device for collecting lunar dust. Background Technology

[0002] Lunar dust is a fine component of lunar regolith, generally referring to lunar regolith particles with a diameter less than 1 mm. Representative lunar dust samples have a median particle size between 40 μm and 130 μm, with an average particle size of 70 μm. Particles smaller than 20 μm account for 10%–20% of the weight. Lunar dust is unbonded particulate matter produced during the Moon's formation process by repeated impacts from meteorites, solar wind, and cosmic rays. It mainly consists of crystalline grains, larger igneous rock fragments, exfoliated debris, and microscopic metallic particles. Lunar dust possesses unique chemical composition, spectral, magnetic, electrical, and micromechanical properties, making it an important sample for studying the interaction between lunar surface materials and the space environment. It also holds significant research value for ensuring the safety of astronauts and operational agencies on the lunar surface. However, current research on lunar dust samples has limitations, lacking detailed analysis of its physicochemical properties and formation processes, which restricts a deeper understanding of lunar dust formation mechanisms, natural / anthropogenic dust emission patterns on the lunar surface, and lunar dust migration mechanisms.

[0003] Obtaining lunar dust samples will provide important samples for clarifying the formation mechanism and microscopic products of lunar dust, determining the physicochemical properties and causes of lunar dust, and revealing the mechanism of lunar dust emission and the laws of dust migration and movement. It has important research significance and is also of great engineering significance for ensuring the safety of astronauts and lunar surface activities.

[0004] Currently, there are no dedicated collection devices on the market for collecting lunar dust samples. Mechanisms designed for other purposes are often incompatible with the requirements of independence, contamination resistance, human-machine interface operability, and safety in lunar sample collection, and therefore cannot meet the actual needs of collecting lunar dust samples. Some lunar dust sample collection solutions require carrying multiple 500g box-shaped devices for collection, but these solutions cannot meet the needs of collecting multiple samples at different locations with relatively small weights. Summary of the Invention

[0005] In order to solve one or more technical problems existing in the prior art, the present invention provides a stacked extraction and adhesion device for collecting lunar dust.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: This invention provides a stacked, extractable adhesive device for collecting lunar dust, including a protective shell, an ejector mechanism, and multiple extractable adhesive pads. The protective shell has a flat, hollow structure, and the bottom of the protective shell has an adhesive opening. The multiple extractable adhesive pads are stacked from top to bottom inside the protective shell. Pull-out openings communicating with the adhesive openings are respectively provided on the bottom of the opposite side walls of the protective shell. The ejector mechanism is installed on the top of the protective shell and can elastically press against the protective shell. The protective shell contains multiple removable adhesive pads; the bottom of the opposite side walls of the protective shell are respectively provided with constricted edges extending into the adhesive openings. The opposite sides of the bottommost removable adhesive pad can correspond to the two pull-out openings respectively and can be pulled out from either of the pull-out openings. The other opposite sides of the bottommost removable adhesive pad can overlap the two constricted edges respectively. The bottom surface area of ​​the bottommost removable adhesive pad corresponding to the adhesive opening is the lunar dust adhesive area. The lunar dust adhesive area is flush with the bottom surface of the adhesive opening or protrudes from the adhesive opening by a predetermined height.

[0007] The beneficial effects of this invention are as follows: This invention provides a stacked extraction-type adhesive device for lunar dust collection. Through extraction, it achieves a multi-layered stacked extraction sampling method for multiple collections of lunar dust particles, which can be used for surface particle sampling on the Moon and extraterrestrial bodies. By setting up an ejection mechanism and multiple extraction adhesive plates, this invention allows for the individual operation of the extraction adhesive plates to collect lunar dust. Samples are recovered by pulling out the extraction adhesive plates, and the ejection mechanism automatically ejects new extraction adhesive plates to the working position for the next collection operation. The stacked extraction adhesive plate configuration enables multiple, multi-point, and independent collection of lunar dust particle samples.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, each of the removable adhesive pieces has a pull handle fixed on one of its opposite sides. The pull handle is located outside the protective housing. The protective housing has handle through holes in the middle of its opposite side walls. The handle through holes are connected to the pull opening. The pull handle is movably inserted into the corresponding handle through hole.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it makes it easier for astronauts to operate by setting up a pull-out handle.

[0011] Furthermore, the bottommost pull handle is a straight structure and is located in the middle of the side of the pull-out adhesive sheet, while the remaining pull handles are all L-shaped structures. The operating ends of two adjacent L-shaped pull handles are located on both sides of the straight pull handle.

[0012] The beneficial effect of adopting the above-mentioned further solutions is that by using pull handles of different shapes and arrangements, sufficient operating intervals can be reserved for astronauts.

[0013] Furthermore, the side of the closing edge used to overlap the removable adhesive sheet is a sloping surface, the cross-section of the removable adhesive sheet is a basin-shaped structure, the two side walls of the basin-shaped structure are overlapping side walls, and the outer surfaces of the overlapping side walls are respectively adapted to overlap the two closing edges.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the closing edge is set as a beveled structure, and the cross-section of the pull-out adhesive sheet is set as a basin-shaped structure, which makes it convenient for the pull-out adhesive sheet to protrude from between the two closing edges for subsequent moon dust adhesion.

[0015] Furthermore, the ejection mechanism includes multiple sleeve assemblies, each sleeve assembly including an outer sleeve, a spring, and an inner sleeve. The top wall of the protective housing has multiple ejection holes, and an outer sleeve is fixed to the outside of each ejection hole. The inner sleeve is movably sleeved inside the outer sleeve. The spring is located inside the inner sleeve and its two ends are respectively connected to the top wall of the outer sleeve and the bottom wall of the inner sleeve. Under the action of the spring, the bottom wall of the inner sleeve extends into the protective housing from the corresponding ejection hole and elastically presses against multiple removable adhesive tabs.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting multiple sleeve assemblies, a stable ejection force can be applied to the removable adhesive sheet.

[0017] Furthermore, the ejection mechanism also includes a flat plate frame, the bottom walls of the plurality of inner sleeves are respectively fixedly connected to the flat plate frame, and the flat plate frame elastically abuts against the topmost pull-out adhesive sheet.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting a flat plate frame, the multiple inner sleeves can be moved down stably, thereby applying a stable and uniform ejection force to the pull-out adhesive sheet.

[0019] Furthermore, the multiple sets of sleeve assemblies are arranged in a rectangular structure.

[0020] Furthermore, the outer sleeve is a cylindrical structure with an open bottom and a sealed top, and the inner sleeve is a cylindrical structure with an open top and a sealed bottom.

[0021] Furthermore, the top of the protective housing is equipped with an assembly joint for installing an auxiliary operating mechanism, and the assembly joint is hinged to the top support of the protective housing via a damping hinge.

[0022] Furthermore, it also includes an auxiliary mechanism that is detachably connected to the assembly joint via a mounting connector. Attached Figure Description

[0034] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0035] Example 1

[0036] like Figures 1-6As shown, this embodiment of a stacked, removable adhesive device for collecting lunar dust includes a protective housing 1, an ejector mechanism, and multiple removable adhesive tabs 2. The protective housing 1 has a flat, hollow structure, and its bottom has an adhesive opening 15. The multiple removable adhesive tabs 2 are stacked from top to bottom inside the protective housing 1. Pull-out openings communicating with the adhesive openings 15 are respectively provided on the bottom of opposite side walls of the protective housing 1. The ejector mechanism is installed on the top of the protective housing 1 and can elastically press against the multiple removable adhesive tabs 2 inside the protective housing 1. The protective housing 1 has constricted edges 16 extending into the adhesive port 15 on its opposite side walls. The bottom two sides of the bottommost removable adhesive sheet 2 correspond to the two pull-out ports and can be pulled out from either port. The other two sides of the bottommost removable adhesive sheet 2 overlap the two constricted edges 16. The bottom surface area of ​​the bottommost removable adhesive sheet 2 corresponding to the adhesive port 15 is the lunar dust collection area, which is flush with the bottom surface of the adhesive port 15 or protrudes from the adhesive port 15 by a predetermined height. This device stores multiple adhesive sheets in a stacked manner, enabling multiple independent collections of lunar dust samples at multiple locations in a high-vacuum lunar environment. The independent adhesive unit collects lunar dust independently through a pulling / extracting motion and automatically ejects a new adhesive sheet to the working position.

[0037] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, the protective housing 1 in this embodiment adopts a rectangular structure. The protective housing 1 has a first side wall 11, a second side wall 12, a third side wall 13 and a fourth side wall 14. The first side wall 11 and the third side wall 13 are arranged correspondingly and each corresponds to the long side of the rectangular structure. The second side wall 12 and the fourth side wall 14 are arranged correspondingly and each corresponds to the short side of the rectangular structure. The bottom of the first side wall 11 and the third side wall 13 forms a tapered edge 16. The bottom of the second side wall 12 and the fourth side wall 14 is higher than the thickness of at least one pull-out adhesive piece 2 of the first side wall 11 and the third side wall 13 to form the pull-out opening, which facilitates the removal of the bottom pull-out adhesive piece 2.

[0038] Furthermore, such as Figure 2 , Figures 4-6 As shown, in a preferred embodiment, the side of the closing edge 16 that overlaps the removable adhesive sheet 2 is beveled, and the cross-section of the removable adhesive sheet 2 is basin-shaped. The two side walls of the basin-shaped structure are overlapping side walls 23, and the outer surfaces of the overlapping side walls 23 are respectively adapted to overlap the two closing edges 16. The closing edge is set as a beveled structure, and the cross-section of the removable adhesive sheet is set as a basin-shaped structure, which facilitates the removable adhesive sheet to protrude from between the two closing edges for subsequent moon dust adhesion.

[0039] like Figure 1 and Figure 3 As shown, in this embodiment, the top of the protective housing 1 is equipped with an assembly joint 42 for installing an auxiliary operating mechanism. The assembly joint 42 is hinged to the top support 4 of the protective housing 1 via a damping hinge 41. Specifically, the assembly joint 42 in this embodiment can be a quick-release joint commonly used in aerospace, and the damping hinge 41 also adopts a damping hinge structure commonly used in aerospace.

[0040] An optional embodiment of this invention includes an auxiliary mechanism for the stacked, extractable adhesive device for lunar dust collection. This auxiliary mechanism is detachably connected to the assembly connector 42 via a mounting connector. The mounting connector uses a quick-release connector commonly used in aerospace applications, enabling rapid insertion and fixation or rapid disassembly with the assembly connector 42. The auxiliary mechanism in this embodiment typically employs a rod-like structure, such as an operating rod with a handle. The free end of the operating rod can be coaxially fitted with the mounting connector, allowing for rapid assembly and disassembly with the assembly connector 42.

[0041] The removable adhesive pad in this embodiment employs a microstructure with micron-level dimensions (such as coil, brush, or braid), and is made of materials such as polyetheretherketone (PEEK), polyimide (PI), or polyamide (PA), exhibiting adhesive properties. The material of the removable adhesive pad in this embodiment is chosen with sample compatibility in mind; the surface material of the component in contact with lunar dust needs to be selected based on the lowest possible contamination to the extraterrestrial sample, or a surface treatment process that minimizes contamination.

[0042] In this embodiment, the ejection mechanism can be elastically pressed onto the top of multiple removable adhesive pads. During use, the ejection mechanism abuts multiple removable adhesive pads against the closing edge of the overlapping sidewall. The bottommost removable adhesive pad is arranged corresponding to the pull-out opening, but it will not come out of the adhesive opening due to the limitation of the closing edge. The entire stacked removable adhesive device is placed on the lunar surface. The bottommost removable adhesive pad will pick up lunar dust. Then, the removable adhesive pad that has picked up the lunar dust is pulled out and placed into an independently numbered packaging container for return. The removable adhesive pads stacked on the top are pushed to the working position to continue picking up lunar dust at the next sampling point.

[0043] This embodiment presents a stacked extraction-type adhesive device for lunar dust collection. Through an extraction method, it achieves multi-layered stacked extraction sampling of lunar dust particles, enabling multiple collections. This method can be used for surface particle sampling on the Moon and other extraterrestrial bodies. By incorporating an ejection mechanism and multiple extraction-type adhesive plates, lunar dust can be collected by individually operating each plate. The sample is retrieved by pulling out the extraction plate, and a new extraction plate is automatically ejected to the working position by the ejection mechanism in preparation for the next collection operation. The stacked extraction-type adhesive plates enable multiple, multi-point, and independent collection of lunar dust particle samples.

[0044] Example 2

[0045] Based on Embodiment 1, in this embodiment, each of the removable adhesive tabs 2 has a pull handle 21 fixed on one of its opposite sides. The pull handle 21 is located outside the protective housing 1. A handle through-hole 18 is provided in the middle of the opposite side walls of the protective housing 1. The handle through-hole 18 communicates with the pull-out opening, and the pull handle 21 is movably inserted into the corresponding handle through-hole 18. The pull handle facilitates operation by astronauts.

[0046] Furthermore, such as Figure 1 and Figure 3 As shown, in this embodiment, the pull handles 21 of two adjacent removable adhesive tabs 2 are located on the outer sides of the protective housing 1. The spaced-out arrangement of the pull handles provides sufficient operating intervals for astronauts.

[0047] In this embodiment, the bottommost pull handle 21 is a straight structure located in the middle of the side of the pull-out adhesive sheet 2, while the remaining pull handles 21 are L-shaped. The operating ends of two adjacent L-shaped pull handles are located on either side of the straight pull handles. This embodiment uses pull handles of different shapes and arrangements to provide sufficient operating intervals for astronauts.

[0048] Example 3

[0049] Based on Embodiment 1 or Embodiment 2, this embodiment provides a preferred structure for the ejection mechanism, such as... Figure 3 , Figure 5 and Figure 6 As shown, the ejection mechanism in this embodiment includes multiple sleeve assemblies 3. Each sleeve assembly 3 includes an outer sleeve 31, a spring 33, and an inner sleeve 32. The top wall of the protective housing 1 has multiple ejection holes. An outer sleeve 31 is fixed to the outside of each ejection hole. The inner sleeve 32 is movably fitted inside the outer sleeve 31. The spring 33 is located inside the inner sleeve 32 and its two ends are connected to the top wall of the outer sleeve 31 and the bottom wall of the inner sleeve 32, respectively. Under the action of the spring 33, the bottom wall of the inner sleeve 32 extends into the protective housing 1 from the corresponding ejection hole and elastically presses against the multiple removable adhesive tabs 2. By providing multiple sleeve assemblies, a stable ejection force can be applied to the removable adhesive tabs. Preferably, as... Figure 5 and Figure 6As shown, the ejection mechanism in this embodiment further includes a flat plate frame 34. The bottom walls of the plurality of inner sleeves 32 are respectively fixedly connected to the flat plate frame 34, and the flat plate frame 34 elastically abuts against the topmost removable adhesive sheet 2. By setting the flat plate frame, the stable downward movement of the plurality of inner sleeves is facilitated, thereby applying a stable and uniform ejection force to the removable adhesive sheet.

[0050] Furthermore, such as Figure 5 As shown, multiple sets of sleeve assemblies 3 are arranged in a rectangular structure. Specifically, four sets of sleeve assemblies 3 can be used. The flat plate frame 34 is a rectangular frame, and one sleeve assembly 3 is installed at each corner of the flat plate frame 34 to facilitate smooth ejection. Each of the four corners of the flat plate frame 34 is provided with a limiting protrusion ring 35, which can abut and limit the bottom of the inner sleeve 32 of the corresponding sleeve assembly 3 within the corresponding limiting protrusion ring 35. The bottom of the inner sleeve 32 can be fixed to the flat plate frame 34 or not, and the clamping and limiting with the flat plate frame 34 can be achieved by the force of the spring 33.

[0051] Specifically, such as Figure 6 As shown, the outer sleeve 31 is a cylindrical structure with an open bottom and a sealed top, and the inner sleeve 32 is a cylindrical structure with an open top and a sealed bottom. In this embodiment, the top of the outer sleeve 31 can be sealed using a detachable plate, and the outer sleeve 31 can be fixed to the protective shell 1 with bolts. The inner sleeve 32 can be a one-piece molded structure. The outer peripheral sidewall of the inner sleeve 32 slides against the inner sidewall of the outer sleeve 31, and the inner sleeve 32 can move axially relative to the outer sleeve 31, while the spring 33 is always in a compressed state.

[0052] In this embodiment, a stacked, extractable adhesive device for collecting lunar dust is used as follows: During operation, the inner sleeves are pressed downwards by springs. Multiple inner sleeves work together to press the flat frame downwards onto the tops of multiple extractable adhesive pads. These pads abut against the closed edge of the overlapping sidewall. The bottommost extractable adhesive pad is positioned corresponding to the pull-out opening (i.e., the working position), but it will not detach from the adhesive opening due to the limiting effect of the closed edge. The entire stacked, extractable adhesive device is placed on the lunar surface. The bottommost extractable adhesive pad collects lunar dust. After collecting the dust, the extracted adhesive pad is pulled out and placed into an individually numbered packaging container for return. The extracted adhesive pads stacked on top are pushed to the working position to continue collecting lunar dust at the next sampling point.
